@Artemis Cromwell ; Unlike most here I'm just a novice at all this, so weigh my response appropriately.
Perhaps it's just my limited set of readers, but responses to what I've written has generated some very kind reviews regarding the story world's surroundings and sensations. Responses such as
'I could see/smell/taste/hear/feel it clearly, helped me to envision it as though I was there,' though flattering, infers to me something else.
Other folks stories in my limited circle, always focused upon the characters, their dialogue, and action. Reviews focused purely on the characters and action, nothing else. Much like if you watched a movie, and everything behind or around them blurred, was inconsequential and therefor ignored. The differences with my stories was that I supplied a detailed environment, mentioned changes to that environment as the characters moved through it, their sensations and so on. In my work, readers besides mentioning the characters and actions, then spoke in detail about how they could clearly envision every sensation the characters experienced, the world around them...and could really see the character there, and more so, place themselves there.
So, right or wrong, I'm of the opinion that many (not all readers), don't use their imaginations as much as we might hope. If they're not supplied something to work with, they'll simply discount it and focus on the characters and actions
alone. Give them an environment (how much is debatable), and ONLY then will a reader add that to the picture. However, the primary difference between reviews was how other folks stories were discussed as though the reader was a voyeur. In mine, the readers placed themselves there, fully immersing themselves into the story.
Perhaps to make up for my other shortcomings, I'll continue to opt for the latter.
Character descriptions in contrast, I'll detail or not to suit my mood, but never just issue a blunt--5'-4", 120#, dark hair...etc.. Any description will be metered out slowly as needed, recognizing it might alienate a reader and keep them from inserting themselves there.
